Traffic mixing in deterministic two-lane model of Hurricane evacuation

We study the mixing of vehicles on a two-lane highway in Hurricane evacuation. We present the deterministic model of two-lane traffic in which vehicles change the lane by a deterministic rule. We investigate the typical traffic induced by a slow vehicle on the first lane under the open boundary. The escape time of vehicles is determined by their order. The vehicular order changes by traffic mixing. The traffic mixing depends highly on the sensitivity. For high sensitivity, the escape time depends on the initial order of vehicles. For low sensitivity, the lane changing occurs irregularly by stop- and go-waves and vehicles then evacuate irregularly without keeping their initial order. (C) 2007 Elsevier B.V. All rights reserved.
